Approximately 67.4% of patients are white. Approximately 43.2% of patients are female. Approximately 34.7% of patients are BOTH white AND female. Calculate the percentage of patients that are EITHER white OR female. Which probability rule did you use to answer this question? Show your work.

Answer #1

Probability that a patient is white : P(A) = 67.4/100 = 0.674

Probability that a patient is female : P(B) = 43.2/100 = 0.432

Probability that a patient is both white and female : P(A and B) = 34.7/100 = 0.347

By Addition theorem of probability,

P(A or B) = P(A) + P(B) - P(A and B)

Probability that a patient is EITHER  white OR female = P(A or B) = 0.674+0.432-0.347 = 0.759

Percentage of patients that are EITHER white OR female = 0.759*100 = 75.9

In monkeyflower, an allele for yellow flowers (Y) is dominant over an allele for white flowers (y). At an independently assorting locus, an allele for entire petals (E) is dominant over an allele for fringed petals (e). A plant that is homozygous for yellow and entire petals is crossed with a plant that is white and fringed. A resulting F1 plant is then crossed with a plant that is white and fringed, and the following progeny are produced: 20 yellow...
